If you use a GTK+ 2.x based DE, like [[Xfce]], [[LXDE]], gnome-tweak-tool won't work; see {{bug|23644}}. You need to [[pacman|install]] {{pkg|librsvg}}, and set your theme manually in {{ic|{XDG_CONFIG_HOME}/gtk-3.0/settings.ini}} (this is usually {{ic|~/.config/gtk-3.0/settings.ini}}. An example {{ic|settings.ini}} file:

{{Note|There probably are other themes. Some of these themes are available in the AUR. Also, some of them are not usable as is for displaying a GTK+ 2.x panel (light text over light background), so you need to use the provided [http://i.imgur.com/QmeyN.png panel background].}}

If you have GTK+ and QT (KDE) applications on your desktop then you know that their looks do not blend well. If you wish to make your GTK+ styles match your QT styles please read [[Uniform Look for QT and GTK Applications]].

{{Note|See the [http://library.gnome.org/devel/gtk/stable/GtkSettings.html#GtkSettings.properties ''GtkSettings'' properties] in the GTK+ programming reference manual for the full list of GTK configuration options.}}

You can customize your GTK applications' keyboard shortcuts (those are called ''accelerators'' in GTK terminology) by hovering your mouse over a menu item and pressing your desired key combination. However, this feature is disabled by default. To enable it, set

This setting controls the delay between you pointing the mouse at a menu and that menu opening in GNOME. Change this to a setting you prefer. I guess the number is in milliseconds, e.g. 250 being a quarter of a second.

There is some more tweaking to do in your themes gtkrc like explained [http://martin.ankerl.com/2008/10/10/how-to-make-a-compact-gnome-theme/ here] and there's another [http://gnome-look.org/content/show.php/Simple+eGTK?content=119812 theme] that does it all.
